Answer:

484 feet  maximum

Step-by-step explanation:

H(t)=-16t^2+112t+288

The maximum height occurs at the vertex of this graph.  

Let us find the vertex.

vertex x-coordinate = -b/2a

x =  -b/2a = -(112)/ (2*-16) =  7/2 sec.

H(7/2) = - 16 *(7/2)^2 + 112*(7/2) +  288

H(7/2) = -196 + 392 + 288 = 484 feet ..

Natalia begins to find the mean absolute deviation of this data set. She finds the mean of the data and then finds the distance
s2008m [1.1K]
Hello!

To calculate mean absolute deviation, you find the mean, find the distance between each data point and the mean, add up those distances, and divide by the number of data points.

In this scenario, after Natalia finds the distances, she must add them all up and then divide by the number of data points.

I hope this helps!

Answer:

x=3.5

Step-by-step explanation:

We can use proportions to solve this problem.  Put the side of one triangle over the same side of the other triangle.

6           4.2

------ = ----------

5           x

Using cross products

6x = 5*4.2

6x =21

Divide by 6

6x/6 = 21/6

x=3.5
